TI  - Seed coat microsculpturing changes during seed development in diploid and 
      amphidiploid Brassica species.
PG  - 555-66
AB  - BACKGROUND AND AIMS: Seed coat morphology is known to be an excellent character 
      for taxonomic and evolutionary studies, thus understanding its structure and 
      development has been an important goal for biologists. This research aimed to 
      identify the developmental differences of seed coats between amphidiploids and 
      their putative parents in Brassica. METHODS: Scanning electron microscope (SEM) 
      studies were carried out on six species (12 accessions), three amphidiploids and 
      their three diploid parents. KEY RESULTS: Twelve types of basic ornamentation 
      patterns were recognized during the whole developmental process of the seed coat. 
      Six types of seed coat patterns appeared in three accessions of Brassica rapa, 
      five types in B. oleracea, B. nigra and B. carinata, seven types in B. napus, and 
      eight types in B. juncea. There was less difference among seed coat patterns of 
      the three accessions of B. rapa. The reticulate and blister types were two of the 
      most common patterns during the development of seeds in the six species, the 
      blister-pimple and the pimple-foveate patterns were characteristic of B. rapa, 
      and the ruminate of B. oleracea and B. nigra. The development of seed coat 
      pattern in amphidiploids varied complicatedly. Some accessions showed 
      intermediate patterns between the two putative parents, while others resembled 
      only one of the two parents. CONCLUSIONS: The variation in the patterns of seed 
      coat development could be used to provide a new and more effective way to analyse 
      the close relationship among amphidiploids and their ancestral parents.
